Are there any messages related to the tc400b in dmesg when you run that?  Do you have any reason to believe that the lock up may or may not be related to the use of the dahdi_transcode?  Also, did you try dahdi-linux 2.1.0-rc4 specifically (or is the trunk version that you used greater than that version)?

I feel that this is a network issue.

If you would like to do some additional testing, you can run something like wireshark on both ends, and you'll see the packets leave the Asterisk box, but you won't see them reach the other side (or, if they are, they aren't returning back properly).

If you can provide pcap traces of both sides where this is not happening, we would be happy to look into it further.
